There is lots of difference between them. A property lets you get/set data in your class. And an attribute is much different, “an attribute is additional declarative information that is specified for a declaration.”

Example of Property in C#:

publicclassEmployee
{
    publicstring Name { get; set; }
    publicstring Email { get; set; }
    publicstring Address { get; set; }
}

Example of Attribute in C#:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace Learn
{
    classProgram
    {
        [Obsolete("Don't use Old method, use New method", true)]
        staticvoid Old()
        {
            Console.WriteLine("New method executed");
            Console.ReadLine();
        }
 
        staticvoid New() 
        {
            Console.WriteLine("New method executed");
            Console.ReadLine();
        }
 
        publicstaticvoid Main()
        {
            New();
        }
    }
}
